Queensland police say a torture victim has died in hospital, with the man accused of the crime now facing a murder charge.

A Queensland man has been charged with murder after his housemate died in hospital, days after allegedly being tied up, tortured and strangled.

The 51-year-old died in hospital on Thursday. Police found the man with critical injuries when they went to a house at Ipswich, west of Brisbane, on Sunday.

They performed CPR on him and he was rushed to hospital but he did not survive his injuries.

His death means his alleged attacker is now facing a murder charge.

The 50-year-old man was originally charged with attempted murder and torture and was remanded in custody when he first faced court on Monday.

The accused is due to face the Ipswich Magistrates Court on the upgraded charge on Friday.

Investigations into the incident are continuing.
